Intuitive vision, a problem with a person’s ability to see, can be treated medically but not entirely with glasses, contact lenses, laser, or surgery. Poor vision includes complete blindness, partial blindness, severe vision impairment, and impaired eyesight. Vision 20/70 is better in the eye, often affecting adults and adults, but some children may become infected. Also because of a congenital defect, or because of an injury.
Poor vision may cause frustration, because it prevents people from doing some activities quickly and effectively, such as driving, reading, watching television, using computers, or simply walking, imposes social isolation on them, and finding work difficult; Annual.
Signs of poor vision
The signs of poor vision, which parents must pay attention to:
- The child’s eye, which is four months old or more, is dislocated inside or outside, while the eye deviation during the first three months of life is normal
- The inability of the baby to fix his eyes on objects and follow them with his eyes when moving.
- Frequent rubbing of the eye.
- Frequent tears, and eyelash constantly.
- Tilt the head when trying to focus.
- Redness and swelling of the eyes.
- Sensitivity to light, ie inability to look at light.
- Asymmetry of the eyes.
- Repeated closure of one eye.
- The inability to trace objects in the field of vision.
- The complaint is difficult to see, or blurry vision.
- Round objects to see them.
- Redness of the eyelids and swelling.
Diagnosis of double vision
To diagnose a weak vision the doctor may resort to the following:
- Identify the medical and family history of the patient in terms of visual impairment.
- Examine various eye parts such as: eyelids, conjunctiva, lenses, iris, cornea.
- Tests of visual acuity and impaired vision, such as:
- Electro-oculogram.
- Snellen test (Snellen test), a test is done by the demand from the patient to read some of the letters and numbers, which lies about six meters away, using each eye separately, or both together to measure visual acuity.
- Visual Field Test, which is designed to determine the patient’s ability to see objects without tilting or rotating the head.
- Tonometry test.
- Ocular Motility Assessment.
- Visual evoked potential.
- Electrical retinal layout (ERG – Electroretinography).
Causes of double vision
Among the reasons that lead to the weakness of the following consideration:
- Exposure to injury, or blow to the eye.
- Genetic factors.
- Lazy eye, or poor eyesight, which leads to ignoring the brain messages from them.
- Cataracts, which prevent the passage of light easily through them, the vision becomes foggy, colors are dim, and the ability to see the presence of dim light.
- Retinopathy and damage to blood vessels caused by diabetes.
- Glaucoma (Glaucoma): A disease caused by increased pressure inside the eye, which leads to damage to the optic nerve and visual impairment.
- Macular degeneration (macular degeneration) is the degradation of the macula, the region responsible for the central vision of the retina. The disease often affects the elderly, but may also affect young people.
- Trachoma: A disease caused by bacteria called chlamydia chlamydia, or chlamydia, Chlamydia trachomatis ).
- The lens responsible for vision in the brain is exposed to hypoxia, injury, or inflammation, which causes cortical blindness (loss of vision due to an organic defect in the visual cortex) leading to impaired vision, temporary or blindness.
- Injury to the palate, or leprosy, is a congenital disorder in body pigments.
- Infection with retinal cytomegalovirus, a common disease among people with AIDS.
- Inflammation of the thyroid tumor, a type of eye cancer.
Eye protection tips
Among the tips that can be followed to protect the eye and prevent its problems:
- Maintain a healthy weight.
- Adjust the level of cholesterol, sugar, and blood pressure.
- Wear sunglasses to protect your eyes.
- Eat healthy foods rich in antioxidants such as leafy vegetables, wild grapes, and red onions.
- Wear protective glasses when needed.
- Refrain from smoking and drinking alcohol.
- Direct air conditioner openings in the car away from the eyes to protect against dehydration.
- Exercise, or physical activity regularly.
- Keep the house temperature low to protect the eye from dehydration.
- Avoid salty food.
- Refurbished eye cosmetics every year, and mascara every three months to avoid contamination of the eyes with bacteria.
- Use swimming glasses to protect eyes from chlorine.
- Sit in a good lighting room when working on a computer, and rest your eyes regularly.
- Check with your eye doctor and regularly check your eye.
Food is essential for eye safety
Of foods beneficial to eye health, prevention of poor vision:
- Foods rich in vitamin C are essential to the health of the blood vessels in the eye, preventing cataracts. Vitamin C is found in red peppers, strawberries, papaya, and cauliflower.
- Vitamin E-rich foods essential for the prevention of cataracts, and prevention of progression of macular degeneration associated with aging. Vitamin E is found in nuts, peanut butter, and sunflower seeds.
- Dark leafy vegetables rich in vitamin C, vitamin E, lutein compounds, zeaxanthin, and carotenoids such as turnip, spinach, and cabbage.
- Omega 3-rich foods that protect the eye from glaucoma, age-related macular degeneration, and maintain eye moisture. Omega-3 is found in fatty fish, such as salmon, tuna, and other seafood.
- Vegetables and fruits are orange, such as carrots, apricots, sweet potatoes, melons and mangoes, because they contain a high percentage of beta-carotene, which helps with night vision.
- Zinc-rich foods, for its role in supplying the retina with vitamin A essential for the production of melanin. Zinc is found in oysters, lean meats, and poultry.
- Legumes, such as beans, lentils, lobsters, and chickpeas, because they help to see at night and reduce the progression of macular degeneration related to aging.
- Because it is rich in compounds that protect the retina, it increases the amount of pigments that protect the spot (part of the eye controls the central vision).
- Gourd and squash because they contain lutein compounds and zeaxanthin.
- Broccoli and Brussels sprouts, because they contain antioxidants that protect the eye from free radicals that attack the retina.
